I don't call myself anything. Other people, however, have informed me that I am a "geek". So, if I had to call myself something, it would be "geek". Sometimes I do something geeky called "programming computers". I hate the word "cracker" since it already has a mundane meaning and a pejorative meaning (small biscuit and poor white Southerner, respectively). I think using the word "hacker" to refer to oneself is a bit haughty. Generally the people I see using it deserve to do so, so I can't complain, but I wouldn't use it myself. If you do find a new word for "hacker", I'll still be a "geek". But good luck. :)
